Students explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then describe the process by which chlorine or bromine compounds can break down ozone molecules.

Students examine the indigenous religions of China (Daoism) and Japan (Shinto) to see how magical beliefs and practices form an integral part of these religions. This lesson may be controversial.

Students predict the product of chemical reaction using the solubility rules. In this chemistry lesson, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Students discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.
